Medium access control protocols for multimedia traffic in wireless networks

This article presents a survey on medium access control protocols for multi media traffic in wireless networks. A basic overview of MAC protocol concep ts is presented, and a framework is developed on which to base qualitative comparisons. The MAC protocols covered in this article include third-genera tion TDMA and CDMA schemes intended for use in a single-hop wireless system . The operation of each protocol is explained, and its advantages and disad vantages are presented. Finally, a qualitative comparative outline of the d iscussed protocols is provided, based on multimedia traffic requirements.
